Analysis of combustion duration and residual gas in secondary explosion of coal dust
Gong-kuang zidonghua, 2018 Secondary explosion experiments of coal dust were carried out by use of 20 L spherical explosion device under the conditions of different coal dust concentration, particle size and ignition energy separately, and influence of coal dust concentration ...

Prediction of heterogeneous nucleation condensation effect on the surface of respiratory coal dust and test of dust reduction test [PDF]
Meitan xuebaoSurface wettability of coal dust particles is an important factor restricting the efficiency of wet dust removal. Heterogeneous nucleation condensation on the surface of coal dust particles is a means without any pollution, without considering the ...

Marcasite at the Permian‐Triassic Transition
Geophysical Monograph Series, Page 377-399., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Use of mineral magnetic concentration data as a particle size proxy: a case study using marine, estuarine and fluvial sediments in the Carmarthen Bay area, South Wales, U.K. [PDF]
, 2005 Compositional (non-magnetic) data can correlate strongly with particle size, which deems it appropriate as a particle size proxy and, therefore, a reliable means of normalising analytical data for particle size effects.

Minor effect of physical size sorting on iron solubility of transported mineral dust [PDF]
, 2011 Observations show that the fractional solubility of Fe (FS-Fe, ratio of dissolved to total Fe) in dust aerosol increases dramatically from ~0.1% in regions of high dust mass concentration to 80% in remote regions where concentrations are low.

Research of influence factors on characteristic parameters of coal dust explosio
Gong-kuang zidonghua, 2014 Influence of particle size, concentration and ignition energy of coal dust on the maximum pressure and its rising rate of coal dust explosion were researched by use of 20 L spherical explosion equipment. The research results show that under the condition
